To ell whom it muy concern:

lie it known that l, (.lUsrAvE lllznssininn, {initiaen of` the Freneli'epublid Aand resi- (lent of Paris, France, have invented certain newand useful inprovenients in 'llluininatinn'lod-ics, of which thefollowing specilieation.

yllie present invention relates to an iin-v proved device for theconstruction of electric illuminating); bodies, such as signs, let ters,Words, lirul'es, ornaments and the like, for the purpose-ef obtaining atlittleA expense very elegant illuminating bodies coinprisiugir a verygreat number of lainps of low voltage and adapted to Work with theordinary current. The electric connections are arranged. so that theextinction of any one of the lamps does .not interfere with the properWorking 'of the other lamps,

lu the accompanying drawings a luminous sign, coiistrueted according' tethe present invention shown by way of example.

Figure l is a front viewl of the saiueglli Q is a seetion drawn on alarger scale on line A-B' of Fig. l; Fig. 3 is a cross seetion on,

a larger scale; Fig; L represents avinodiication; Fig. 5 is a front viewof Fig. 4.

The sign, ornament,'letter, figure, ete., to

be represented, is out out of a plate of insu lating material and saidplate e has as many holes o as there are lamps required; the eap fi oit'each lamp being fixed in its hole 0. The holes o are enlarged at therear ends and Vin said enlarged parts e Cups f with spiral springs y]are located.

According to the voltage E of the line and to the voltage g of the lampswhich are used, said lamps are divided into groups,

the lamps being connected in each group in shuntand the groups being;connected in series upon plate o. lf N represents the total nun'ibeieflamps rf. which have to constitute the luininous sign, each group willline is supposed to be .of 112 volts and the lamps a. ol the noi-unil.voltage of ley volts. The sign comprising 28() lamps, said lamps Awillbe dividedinlo 8 groups of larnps each. To put said groups in series, aeerv tain number of conducting,r plates t, ft2 to l are mounted upon theupper face of plate ai, said plates being separated by 'insulatingspaces t, s, 97,' Q. Each plate it serves to @unification of LettersPatent. .Application filed January G. 1869.

carry the lanips of two groups, or 70 lan-ips for Wine-h purpose theplate liasholes Whieh correspond to the' holes c andv are 'threaded@responding to the thread of the 5i lamp-caps. rhe two end plates f1.5and h' carry only the lamps of one group, or 35 lamps.4 llpon the lowersurface of insulating plate o.. otherconducting yplates m to m* arearranged. which are separated by insu,

la ting spaces 037e', u and which serve as supv ports for' spiralsprings which through the intermedia-ry of cups f insure the electriceonneetien of each lamp b. (SeeFig, 3.)

`The plates m serve each 'for 70 lamps' and they are arranged so thatthe, insulating spaces and n of plates k .L' and m do not c0- ineidebut' alternate in such a manner that there arenever moreI than 35 lampsbetween two consecutive insulating spaces (see Fig.-

l). The current arrives, for example, by

the lower end platee', flows through the first group of lainpsbf, and soonearried by said plate, to be conducted by means rof the rst of theplates fm, .designated m into the lamps b2 of the seeond group, to flowthrough `the plate L to the lamps b3 of the third group and so on tollow'out of 'the apparatus through the last strip i. Thus, if thecurrentge'ts into one'group of lamps by means of a plate It it willgetinte the tivo adjacent groups of lainps by means of .plate m.

lf a-'signboard is to be constructed, the sign to be formed can eitherbe cut out of a plate of insulating material or it can Ybe composed ofseveral parts, said parts being one insulating plate showing the lshapeof the sign to be represented.

For certain purposes it Will be advantagenus to be able to easily taketo pieces the illui'i'iinating body,` particularly if the same foi-inslong rods; inthis ease Vthe rod willl Thus a rod .or bar of any lengthcan be formed by connecting the required number of elements. rhoelements will pre'l'eraldy bel connected by 'means of t screw bolts zwhichfare screwed through one section of insulating plateJc and into oneof the platesv v lw'or 1 belonging to said section of insulatnation alate of insulating material which Ahas they e ape of the .sign to berepresented pzate k and intothe 'section of the plate 'g/ or iorespectively of theadjacent element. If the screw bolts z be,jthus'arranged, the 'different elements will be connected in series.

It is evident` that With the improved illuminating vbi'dy very artisticluminous devices can be con- .vstructed; by using lamps of 10W voltage(Ll 'or'lO volts for ,examplel-and of one candlepower there will beobtained Withoutpany practical inconvenience, an eXtreme..d'1v1- lsionof thefluminous lintensity which. is at thesamg time very economical andvery ad'- vantage us With'regard to the arustie effect.
